Re: [PATCH 4/3] fixup! reftable: add dump utility

Carlo Marcelo Arenas Belón  [off-list ref] writes:

avoid _XOPEN_SOURCE in alpine by making sure git-compat-util.h is included
first (through hash.h) as recommended and therefore avoid:

The headers cache.h and builtin.h are the only ones whose inclusion
allows the source to omit an explicit inclusion of git-compat-util.h
and we'd prefer the inclusion of git-compat-util.h to be explicit
here, not through hash.h.  Just including git-compat-util.h directly
without moving inclusion of hash.h should be sufficient.
